llNDiCATilNG DEVTQE llctcr A. iieresiord, 22 Forest Drive, Town of Qoiorne, Aihany 5, li iied Apr. 16, 1962, Ser. No. 157,557 1 (Chaim. (Cl. b--43) This invention relates to a device by means of which international standard time is indicated throughout the principal cities and countries in the world.

Therefore it is the object of this invention to provide a device having a minimum of parts, inexpensive to manufacture that will indicate the time, both forenoon and afternoon, contemporaneously in the principal cities and countries throughout the world.

This object and other objects of the invention should be appreciated from the detailed specification taken in conjunction with the drawing showing an oblique view of the embodiment of the invention.

Reference numeral 1 generally refers to the device having a suitable housing 3 and handle 5 suitably screwed to the top portion of housing 3 for ease in movement of the device.

Extending through front plate 9 secured to housing 3 by four screws 7 is a drive shaft (not shown) driven one revolution in twenty-four hours by a suitable electric drive motor (not shown) housed within housing 3.

Arranged freely on the drive shaft is a movably twentyfour hour time dial ill numbered 1 to 12 and 1 to 12 thereon to designate the twenty-four hours of the day.

The morning portion of dial 111 from 6:00 am. through noon to the afternoon portion ending at 6:00 pm. is of light color to contrast with the dark color of the evening portion from 6:00 p.111. through the night to early morning portion ending at 6:00 am.

Knob 13- is co-rotatably mounted on the drive shaft and by means of a suitable slip-clutch (not shown) utilized structurally with knob 13 and the drive shaft, movement of knob 13 in one direction relative to the drive shaft may be effectuated. The significance of this feature for purposes of setting the time to correspond with the correct time for a particular city should be appreciated. In this connection it should be further appreciated that such a result is obtainable because knob 13 structurally is in frictional engagement at all times wtih dial 11.

Radially extending from dial 'llll are twenty-four sectors 15 within which, for ease in the reading of same, are horizontally arranged and disposed cities and countries corresponding to the position of the cities and countries time-wise relative to international date line 17. Circumferentially arranged on dial 11 are equally spaced marks 19 to designate the time by quarter hour, half hour, threequarter hour and hour.

Interposed between dial Jill and sectors 15 is an annulus shaped band 21 on front plate 9 which is concentric with dial 1111. Band 21 is made up of alternating light color valleys 23 and dark color peaks 25. The valleys 23 have radial marks 27 arranged in the center thereof as a guide for ease in setting the time of the dial 1-1 to correspond to the correct time of the city.

On the front plate 9, the city of New York is arranged thereon in the top dead center position for purposes of ease in setting of the time for eastern standard time and indication to those in the eastern standard time zone of the time in the rest of the world.

Sufiice it to say that it is within the scope of this invention that any city or country may be arranged in the top dead center position to afford the residents of that particular city or country the ease in the setting of time afforded to residents of the eastern standard time zone.

In using the device one would merely manipulate knob 13 sufiiciently to position dial ill in the position where the radial mark 27 of its sector 15 will line up with the time on dial A; corresponding with the correct time of the city or country of that sector. The correct times for the other cities and countries on front plate 9 will thereby be indicated by reference to their respective radial marks 27.

This particular simplification achieved in indicating time throughout the world by means of the contrasting light and dark portions on dial 11 should be appreciated. For example, should a businessman desire to place a business telephone call to Tokyo at 4:00 pm. eastern standard time, he would need only glance at the sector 15 containing lapan to readily ascertain that it would then be 6:00 am. Tokyo time with business ofiices closed at that time.

Having thusly described my invention, 1 claim:

An international standard time device for indicating the time of the principal cities and countries throughout the world, comprising a time dial, a front plate having twenty-four sectors radially extending from said time dial and the principal cities and countries horizontally arranged and disposed within said sectors time-wise in their positional arrangement relative to the international date line; said time dial being numbered consecutively and in equal space arrangement thereon l to 12 and l to 12 to designate the twenty-four hours of the day with equally spaced marks circumfe-rentially arranged on said time dial to designate for each hour the time by quarterhour, half hour, threequarter-hour and hour, and for ease in reading and appreciating the significance of said time dial the morning portion of said dial from 6:00 oclock in the forenoon through to the portion at 6:00 oclock in the afternoon being of a light color to contrast with the dark color of the portion of said time dial from 6:00 oclock in the afternoon through to the early morn ing portion ending at 6:00 oclock in the forenoon; an annulus shaped band on said front plate concentric with said time dial and interposed between said time dial and said sectors with alternating light color valleys and dark color peaks alternately arranged and disposed with said annulus shaped band for purpose of further ease in reading and appreciating the time on said time dial and with radial marks arranged in the centers of the light color valleys as a guide for ease in setting the time of the dial to correspond to the correct time of the city.
